Abstract

The invention discloses a display panel and display equipment. An optical fingerprint identification sensor and an optical gesture recognition sensor are integrated with the display panel, and a device and a module are not needed to be set outside the display panel to realize fingerprint identification and / or gesture recognition; and the display panel can also realize gesture recognition and / or fingerprint identification on the basis of realizing a display function, thereby increasing the use added value of the display panel. The display panel provided by the embodiment of the invention comprises an optical sensor structure used for fingerprint identification and / or gesture recognition, and the optical sensor structure comprises a light emitting layer and a photosensitive sensor.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the prior art, the Time of Flight (TOF) gesture recognition technology uses a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) camera to capture the two-dimensional coordinates of the gesture, and uses a photosensitive sensor array to emit and detect reflected light to calculate Gesture depth coordinates realize gesture recognition, and the functional modules for realizing gesture recognition in the prior art are completely external. [0003] The current fingerprint identification devices of the display panel are capacitive and ultrasonic, each has its own advantages and disadvantages, but a common defect is that the sensing distance of the sensor is short, which severely limits the structure and performance of the fingerprint identification device and affects ...
